Fully Built Pinewood Derby Car (2024)

FAQs

What is the fastest Pinewood Derby car shape? ›

No need to get crazy here, but simply having a wedge-shaped Pinewood Derby car instead of the standard block out of the box will equal a 1.4-car advantage at the finish line.

The wedge is a classic and probably the easiest shape (besides keeping a block) to build your Pinewood Derby car. The Wedge is the foundation of many cool car designs, and it is designed to be aerodynamic and is a one-cut wonder.

Three areas on a Pinewood Derby® car must be aligned; failure to do so leaves speed on the track! The rear wheels should be set at a 3-degree angle (camber). This angle reduces friction as only a tiny portion of the wheel makes contact with the track.

Slide the axles and wheels onto the car and glue into place. Use an epoxy or nonresin glue, and make sure you don't get any on the surface of the axle where the wheel rides.

Assuming all other factors are equal, a heavier car will be faster than a lighter car. The Pinewood Derby rules limit the weight of each car to 5 ounces.

In most races, the maximum allowable weight of a pinewood derby car is five ounces. By meeting this maximum limit – while also strategically placing your weights at the rear of your vehicle – you will improve your momentum and increase the distance your car travels towards the finish line.

Much has been written about the physics of pinewood derby cars, and this is one rare case in racing where heavy = fast. Aerodynamics have little effect in such a short race, but weight does and putting the weight at the back of the car will make your car faster on the flat of the track.

However, as with most facets of Pinewood Derby®, there is a trade-off between speed and stability regarding wheelbases. The shorter the wheelbase, the more potential there is for speed. However, the shorter wheelbase can also lead to instability, slowing the car.

PUT MOST OF THE WEIGHT IN THE BACK

Science says the heaviest part of your car should be about 1 inch in front of the rear axle. The idea is that the farther back the weight is, the more potential energy you have because your center of mass is higher up on the track.

“He set the track record in NYC with a 2.93 second run, which wasn't even approached by any other car up there.” JJ's car was apparently the only car at the event to average under 3 seconds. Brewster says 3 seconds is sort of the “holy grail” of the Pinewood Derby Racing Leagues.

Does paint add weight to a Pinewood Derby car? ›

(paint will add very little to the weight of your car). When your car is complete, weigh it again. If it is over 5 oz, drill a few holes in the bottom of the block about an inch behind the front axle to remove some wood. Below are several suggestions for adding weights to your pinewood derby car.

Push until the wheel touches the car body. The base is designed to leave the proper gap between the wheel and body. 5. The axle will need to be glued if it slips easily into the car body.

Bent axles can be used to: Reduce friction. Align the car to run straight. Adjust the car to use the rail riding technique.

PUT MOST OF THE WEIGHT IN THE BACK

Science says the heaviest part of your car should be about 1 inch in front of the rear axle. The idea is that the farther back the weight is, the more potential energy you have because your center of mass is higher up on the track.

Best Location to Weight Your Pinewood Derby Car

When deciding on where to weight your car, you should try to reach a final balance point of the car 1 inch or less in front of the rear axle. To achieve this, place 2/5 of the added weight behind the rear axle, and the remaining 3/5 in front of the rear axle.

Crafting the Design: Outline your Pinewood Derby car on paper, cut it out, and affix it to the wood block. Remember, a rectangular car is not an aerodynamic design. The most basic aerodynamic design is a simple wedge. If you don't have time to design a complex car, a wedge will work just fine.
